Trane BKR1872 Circuit Breaker 321042-401 This microprocessor-based ignition control is

This microprocessor-based ignition control is designed with no pre-purge (0-second) and a 15-second trial for ignition (TFI)

the SC25S-B signal conditioner overrides the external BMS signal to protect the heat exchanger from overheating or to prevent cold drafts

The rugged aluminum construction ensures long-term reliability in demanding HVACR environments

using it on smaller tonnage units may lead to improper refrigerant metering

Trane BKR1872 Circuit Breaker 321042-401 This microprocessor-based ignition control isThe Trane BKR1872 Circuit Breaker is a critical electrical safeguard designed for high demand HVAC overcurrent protection. As a 60 amp double pole breaker, this component provides essential protection for residential and light commercial systems, including air handlers, heat pumps, and condensing units. It is engineered to handle a 230V (up to 240V AC) electrical load, ensuring that both lines of the circuit are simultaneously monitored and protected
