Why Choose the IMO C4M11 Magnetic Trip Alarm?
The IMO C4M11 is a magnetic trip alarm auxiliary contact designed specifically for IMO C4/32R motor circuit breakers. It provides a dedicated short-circuit trip signal, allowing the cause of a breaker operation to be communicated to an external indication, monitoring or control circuit.
Featuring 1 normally open (1NO) and 1 normally closed (1NC) contact, the C4M11 provides complementary auxiliary outputs for integration into industrial control systems. Its left-hand side-mounted design keeps the accessory closely integrated with the motor circuit breaker and supports compact control-panel layouts.
A maximum of one C4M11 magnetic trip alarm can be installed per compatible circuit breaker. By providing a specific signal following magnetic short-circuit operation, the accessory can help maintenance personnel and control systems distinguish this event from normal circuit breaker switching.
Key Advantages
- Provides a dedicated short-circuit trip signal from a compatible motor circuit breaker.
- Features 1NO + 1NC auxiliary contacts for flexible signalling arrangements.

Dedicated Short-Circuit Trip Signalling
A magnetic trip alarm provides additional information beyond the basic open or closed state of a motor circuit breaker. When the magnetic protection mechanism operates in response to a short-circuit condition, the C4M11 provides an auxiliary signal that can be incorporated into an appropriately designed indication or control circuit.
This dedicated signalling capability can be particularly useful in industrial installations where operators or automation systems need to identify protection events quickly. With its 1NO + 1NC contact arrangement and direct side mounting to the C4/32R breaker, the C4M11 provides a compact method of adding magnetic trip indication to a motor protection assembly.
Typical Applications
- Short-circuit trip indication for motor protection systems.
- Industrial motor starter assemblies.
- Machinery control and monitoring panels.
- PLC and automation signalling circuits.
- Fault indication and alarm systems.
- Pump, fan and conveyor motor control installations.
