Why Choose the ABB 1SCA022812R7420 OTP125BA3M Enclosed Safety Isolator?
The ABB 1SCA022812R7420, order code OTP125BA3M, is a robust 125 A three-pole enclosed safety isolator designed for dependable switching and electrical isolation of industrial machinery, motors and electrical equipment. As part of ABB's metal-enclosed load-break product group, the OTP125BA3M combines high-capacity switching with a durable glass-reinforced polycarbonate enclosure.
The OTP125BA3M provides an IP65 protection rating and an IK08 impact-resistant enclosure suitable for indoor and outdoor industrial applications. Its red/yellow selector-type I-O / ON-OFF handle is padlockable for secure maintenance isolation, while the interlocked enclosure cover helps prevent access when the switch is in the ON position. The interlock can also be bypassed by authorised personnel for procedures such as thermographic inspection.
With an authoritative 125 A rating and three-pole configuration, the ABB OTP125BA3M provides AC-22A switching at 125 A and AC-23A switching at 90 A across 380–415 V. It also supports a 45 kW AC-23A motor load at 380–415 V, making it suitable for substantial three-phase machinery and motor isolation applications.
