Q270 | Siemens 70 Amp Circuit Breaker

The Q270 is a Siemens 70 Amp circuit breaker. It belongs to the Siemens QP series, known for its reliable performance and ease of installation. The circuit breaker is designed for use in Siemens type EQ, EQL, SEQ, EQG, PL, and ES series load centers. The Q270 breaker features a plug-in connection type, facilitating quick and efficient installation. 

This circuit breaker has a voltage rating of 120/240 VAC and a frequency rating of 60 Hz, making it suitable for a variety of residential and commercial applications. It is a two-pole device, providing a robust solution for circuits requiring double protection. The Q270 is capable of handling a current rating of 70 amps, which is sufficient for most moderate to high load applications. 

The interrupting rating of the Q270 is 10,000 amperes, indicating its ability to safely interrupt a short-circuit or overload condition without damaging the electrical system. This feature is crucial for maintaining safety and preventing electrical fires. The frame of the circuit breaker is designated as QP, and it employs a thermal magnetic trip type, which provides both long-time and instantaneous protection. This combination ensures that the breaker responds promptly to both sustained overcurrents and sudden short circuits.
