The ABB OTP45BA4M is a robust 4-pole, IP65 plastic enclosed switch-disconnector designed for dependable manual switching and electrical isolation in industrial machinery, motor installations and low-voltage distribution systems. Part of the ABB OTP enclosed switch range, it combines a durable grey enclosure, a highly visible red and yellow operating handle and a four-pole switching mechanism in one complete assembly.
The OTP45BA4M is identified by the supplied product specification as a 15 kW, 4-pole enclosed switch. ABB's published technical data also specifies a 22 kW AC-23A motor switching rating at 380–415 V AC and a 15 kW rating at 690 V AC. Its rated operational current is 45 A AC-23A at 380–415 V AC, making it suitable for appropriately rated motor and inductive-load switching applications.
Featuring an IP65-rated grey plastic enclosure, IK08 impact resistance and a red and yellow selector-type operating handle, the OTP45BA4M is designed for demanding industrial environments. It includes neutral and protective earth terminals, an interlocked enclosure cover with a defeatable interlocking facility and metric cable-entry knockouts for flexible installation.
The ABB OTP45BA4M provides a practical means of manually switching and isolating low-voltage electrical circuits where a four-pole configuration is required. Its integrated switching mechanism allows the designated conductors to be operated together through one external handle, making it suitable for appropriately designed three-phase and neutral switching arrangements.
ABB specifies a 45 A AC-23A operational current rating at 380–415 V AC, corresponding to a 22 kW motor switching rating. At 690 V AC, the AC-23A motor switching rating is 15 kW. These figures demonstrate why the applicable supply voltage and utilisation category must be considered when selecting an enclosed switch-disconnector.
The four-pole configuration provides additional switching capability compared with conventional three-pole units. The OTP45BA4M is described by ABB as having a fixed and switchable neutral arrangement, making it suitable for installations where the neutral configuration must be considered as part of the overall electrical design.
The external red and yellow selector handle provides clearly marked ON and OFF positions. It is padlockable with up to three padlocks, supporting controlled maintenance isolation procedures. The enclosure cover is interlocked with the operating mechanism and incorporates a defeatable interlocking facility for authorised access in accordance with ABB's installation instructions.
The IP65 grey plastic enclosure helps protect the switching equipment against dust ingress and water jets. Its IK08 impact resistance provides additional mechanical durability. The enclosure includes 2 × M32 + M16 metric cable-entry knockouts at both the top and bottom, allowing suitable cable glands to be selected for the installation.
For electrical integration, the OTP45BA4M includes neutral and protective earth terminals. No auxiliary contacts are fitted as standard, but compatible accessories can be selected where auxiliary signalling is required, up to the manufacturer's specified maximum arrangement of 2 normally open and 2 normally closed contacts.
The OTP45BA4M is a manual switch-disconnector rather than an automatic circuit breaker. It does not independently provide overload or short-circuit protective tripping. Suitable upstream protection, conductor sizing, earthing arrangements and safe isolation procedures must be incorporated into the complete installation.

The ABB OTP45BA4M is a four-pole plastic enclosed switch-disconnector used for manual switching and electrical isolation in industrial machinery, motor installations and low-voltage distribution systems. It features an IP65 enclosure and a red and yellow operating handle.
The OTP45BA4M has four switching poles. It is designed for applications requiring four-pole operation, including appropriately engineered three-phase and neutral switching arrangements.
The OTP45BA4M has a rated operational current of 45 A under AC-23A conditions at 380–415 V AC and 63 A under AC-22A conditions at the same voltage range. Its conventional thermal current when fully enclosed is 63 A.
The supplied product description identifies the OTP45BA4M as a 15 kW switch. ABB's published AC-23A ratings specify 22 kW at 380–415 V AC and 15 kW at 690 V AC. The applicable motor switching rating therefore depends on the operating voltage.
The OTP45BA4M has an IP65-rated plastic enclosure, providing protection against dust ingress and water jets when correctly installed. The enclosure also has an IK08 impact resistance rating.
The OTP45BA4M features a red and yellow selector-type rotary operating handle with clear I–O and ON–OFF position indication. The enclosure is grey plastic.
Yes. The OTP45BA4M has a padlockable operating handle that can accommodate up to three padlocks. This supports controlled electrical isolation and lockout procedures when used in accordance with site safety requirements.
No auxiliary contacts are fitted as standard. The OTP45BA4M supports a maximum auxiliary contact arrangement of 2 normally open and 2 normally closed contacts when suitable compatible accessories are installed.
Yes. The OTP45BA4M includes a neutral arrangement described by ABB as fixed and switchable neutral, together with protective earth terminals. The complete wiring arrangement must follow the manufacturer's instructions and applicable electrical regulations.
The OTP45BA4M has 2 × M32 + M16 metric cable-entry knockouts at both the top and bottom of the enclosure. Suitable cable glands must be selected separately to maintain the required ingress protection.
The OTP45BA4M enclosure measures 200 mm high × 145 mm wide × 90 mm deep. Its approximate net weight is 0.9 kg.
Yes. The OTP45BA4M includes an interlocked enclosure cover designed to restrict normal opening while the switch is ON. A defeatable interlocking facility is provided for authorised access in accordance with the manufacturer's instructions.
The OTP45BA4M is a four-pole enclosed switch-disconnector, while the OTP45BA3M is a three-pole variant. The correct model should be selected according to the number of conductors that must be switched and the electrical installation requirements.
No. The OTP45BA4M is a manually operated switch-disconnector and does not independently provide automatic overload or short-circuit tripping. Suitable protective devices must be selected separately for the electrical installation.
The ABB manufacturer part number for the OTP45BA4M is 1SCA022459R6860. The model belongs to ABB product group 311004 – Plastic Enclosed Switches (OTP).
ABB OTP enclosed switch-disconnectors are designed to provide dependable manual switching and electrical isolation for industrial machinery and low-voltage electrical installations.
