B-LINE A2L5RPK – Frequently Asked Questions
1) Which Eaton breakers does the A2L5RPK alarm switch fit?
The A2L5RPK is an Eaton Series G molded case circuit breaker accessory built for N-frame breakers. If your breaker is a different frame size, this internal accessory won't mount, so match the frame designation on the breaker label before ordering.
2) How many contacts does the A2L5RPK alarm switch give me, and how do I wire it?
Contact configuration is 2 MK-2 BK, and it lands on pigtail leads rather than screw terminals. Plan for a splice or terminal block inside the enclosure, and leave enough gutter space to dress the leads out to your monitoring point.
3) Does the Eaton A2L5RPK mount on the left or right side of the breaker?
Right side. The mounting method on the A2L5RPK is right-pocket, so if you already have another accessory occupying the right internal pocket on that N-frame breaker, you'll need to move it or choose a left-mount accessory instead.
4) What does an alarm switch on a molded case breaker actually do?
It signals that the breaker has tripped, as opposed to being switched off by hand. The A2L5RPK is catalogued as an alarm lockout accessory for Eaton Series G N-frame breakers, and its contacts change state on a trip so a panel light, BMS point, or annunciator can pick it up. If you instead want a contact that follows the handle position on every open and close, that is an auxiliary switch, not this part.
5) Can I add the A2L5RPK alarm switch to a breaker already installed in a panel?
It's a field-installable internal accessory for Eaton Series G N-frame breakers, so it goes in through the breaker's accessory pocket on the right side. The breaker has to be de-energized and removed or opened up to fit it, which means a planned outage on that circuit rather than a live add.
6) Is the A2L5RPK the right part number if I'm ordering alarm switches for a facility standard?
A2L5RPK is the full Eaton manufacturer part number, and it's a single-configuration item: Series G, N-frame, right mount, 2 MK-2 BK contacts, pigtail leads. There are no finish or size options to specify, so a repeat order for a fleet of N-frame breakers is just quantity against that one number.
