Why Choose the ABB 1SDA085699R1 250 V AC Second Trip Signalling Contact?
The ABB 1SDA085699R1 is a genuine second trip signalling contact for compatible ABB SACE Emax 2 air circuit breakers. Also identified as the S51/2 second bell alarm contact, it provides an additional electrical indication when the circuit breaker trips.
Designed for 250 V AC signalling circuits, the 1SDA085699R1 is specified for Emax 2 E2.2, E4.2 and E6.2 circuit breaker frames. It supplements the primary trip signalling arrangement, allowing an additional external circuit to receive breaker-trip status for annunciation, supervision or control purposes.
ABB identifies the accessory under global order code 1SDA085699R1 and US/Canada part number ZEBBA2. Its dedicated Emax 2 design provides a manufacturer-specified solution for applications requiring a second 250 V trip-status signalling contact.

Additional Trip Status Signalling for Emax 2
A trip signalling or bell alarm contact provides an electrical status signal following a circuit breaker trip. This signal can be incorporated into external annunciation, supervision or control circuitry so that the trip condition can be indicated away from the breaker itself.
The ABB 1SDA085699R1 provides the second S51/2 trip signalling contact for compatible Emax 2 E2.2 through E6.2 breakers. The additional contact is particularly useful where the installation requires another 250 V AC trip-status signal in addition to the primary bell alarm arrangement.
Typical Applications
- ABB SACE Emax 2 E2.2 air circuit breakers.
- ABB SACE Emax 2 E4.2 air circuit breakers.
- ABB SACE Emax 2 E6.2 air circuit breakers.
- Remote circuit breaker trip indication.
- Switchboard alarm and annunciation systems.
- Industrial control and supervision circuits.
- Low-voltage power distribution systems requiring a second trip-status signal.
