2CDA382799R0981 ABB M302P-D0.5 Magnetic Circuit Breaker 0.5 A Type D 25 kA 2P

Why Choose the ABB M302P-D0.5 Magnetic Circuit Breaker?

The ABB M302P-D0.5 is a compact two-pole magnetic circuit breaker designed to provide short-circuit protection for electrical circuits and equipment. Part of ABB's S200M / S300P circuit protection portfolio, it combines a 0.5 A rated current, Type D characteristic and high breaking capacity for demanding protection applications.

Unlike conventional thermal-magnetic miniature circuit breakers, the M302P-D0.5 uses magnetic-only tripping. This makes it suitable for applications where dedicated short-circuit protection is required while overload protection, where necessary, is provided separately by appropriately coordinated protective equipment.

With a rated short-circuit breaking capacity of 25 kA and a two-pole configuration, the M302P-D0.5 provides robust protection for low-current electrical circuits. Its modular construction supports straightforward integration into DIN rail-mounted electrical control and distribution panels.

Key Advantages

• Magnetic-only circuit protection for rapid response to short-circuit currents.
• 0.5 A rated current for low-current equipment and control circuits.
• Type D characteristic accommodates circuits with comparatively high transient or inrush currents.
• High 25 kA short-circuit breaking capacity.
• Two-pole configuration for coordinated switching and protection.
• Suitable for systems where overload protection is provided separately.

Key Features

• ABB M302P magnetic circuit breaker.
• 0.5 A rated current.
• Type D trip characteristic.
• 25 kA rated short-circuit breaking capacity.
• Two-pole (2P) configuration.
• Magnetic-only tripping mechanism.
• Compact modular construction.
• DIN rail mounting for straightforward panel integration.

Dedicated Magnetic Short-Circuit Protection

The ABB M302P-D0.5 uses a magnetic trip mechanism to respond rapidly when current reaches short-circuit levels. Because it provides magnetic rather than conventional thermal-magnetic protection, separate appropriately coordinated overload protection should be provided where required by the electrical system design.

Its Type D characteristic is suited to circuits where comparatively high instantaneous or starting currents can occur during normal operation. Combined with its 25 kA breaking capacity and two-pole construction, the M302P-D0.5 provides dependable short-circuit protection for demanding low-current equipment and control applications.

Typical Applications

• Industrial electrical control panels.
• Low-current equipment circuits requiring dedicated short-circuit protection.
• Circuits with separately coordinated overload protection.
• Control and auxiliary electrical circuits.
• Loads with relatively high transient or starting currents.
• Machinery and industrial distribution equipment.
