Schneider Electric M9A26946 Shunt Trip Release

The Schneider Electric M9A26946 is a shunt trip release accessory designed for use with Multi-9 circuit breakers. It provides remote tripping capability for electrical distribution systems in commercial and industrial installations. Electrical contractors and facility engineers specify this device to add emergency shutdown or automated control functions to existing breaker panels.

Thermals, noise and power draw

The device operates reliably across a temperature range from -13 °F to 122 °F, covering typical indoor and outdoor panel environments. As a passive electromechanical accessory, it generates no audible noise during normal operation and draws negligible power from the control circuit when idle. Its coil activates only when a trip signal is applied, minimising continuous energy consumption.

Behaviour under sustained load

The release is rated for 6 A at 110/415 V AC and 110/130 V DC, allowing it to handle control-circuit currents continuously without overheating. An integrated OC contact provides auxiliary signalling for monitoring or interlocking purposes during prolonged activation. The unit maintains consistent trip performance over repeated operations within the specified temperature limits.

Questions about this item

How do I wire the M9A26946 shunt trip release to my Multi-9 breaker, and which terminal step is most often missed?

Connect the coil leads to a 110 V AC or 110-130 V DC control circuit; the step installers skip is landing the included OC contact on the breaker's auxiliary terminal so the trip signal actually reaches the mechanism.

What part of the M9A26946 will need replacement first after repeated tripping cycles?

The internal solenoid coil and its OC contact are the wear items; after many operations the contact surfaces can carbonise, requiring a new shunt-trip module rather than a field repair.

At what ambient temperature does the M9A26946 hit its thermal limit during continuous energisation?

The rated maximum operating temperature is 122 °F; sustained use above that level causes the coil insulation to exceed its thermal class and trip reliability drops.
