B-LINE SNT120CPK – Frequently Asked Questions
1) What voltage does the Eaton B-Line SNT120CPK shunt trip coil operate on?
The SNT120CPK shunt trip is rated 120 Vac. If your trip signal comes from a 24V fire alarm relay or a DC control source, this is not the right coil for that circuit; you would need a shunt trip matched to that control voltage.
2) Will the SNT120CPK shunt trip fit any brand of circuit breaker?
No. It is an Eaton Series G accessory and belongs in a Series G molded case breaker. Shunt trips are frame-specific, so a Square D, Siemens, or GE breaker, and Eaton frames outside Series G, take their own accessory. Match the breaker series before ordering.
3) What does a shunt trip on a molded case circuit breaker actually do?
A shunt trip is an accessory coil installed in the breaker that opens it remotely when it is energized. Apply 120 Vac to the SNT120CPK coil and the breaker trips, the same as if it had been switched off at the handle. It is how elevator recall, fire alarm interlocks, and emergency power-off stations drop a breaker without anyone standing at the panel. It does not provide overcurrent protection on its own, the breaker still does that.
4) I need the Eaton part number for a 120V Series G shunt trip for a submittal.
Order Eaton SNT120CPK. It is the Series G shunt trip kit rated 120 Vac, and the manufacturer's spec sheet for SNT120CPK is the document to attach to your submittal.
5) Can I add a shunt trip to a Series G breaker that is already installed?
Yes, the SNT120CPK is a field-installable kit for Series G molded case breakers rather than a factory-only build. The breaker has to be de-energized and removed to fit it, and one accessory pocket is consumed, so if you also plan an auxiliary switch or undervoltage release on the same breaker, confirm the frame has space for both.
