Siemens Q320EQ-P Circuit Breaker

Siemens Q320EQ-P is a 3-pole, 20-amp, 240-volt plug-in circuit breaker from the Siemens Q-series designed for panelboards and Gould EQ-P load centers. This thermal-magnetic device provides 3‑phase overcurrent protection and mounts in compatible Siemens EQ-P or QP panel boards without bolting, simplifying installation and replacement. Rated for a 10 kA interrupting capacity at 240V, it protects feeders on 3‑phase circuits in residential or light commercial electrical systems. The Q320EQ-P is the 20 A, 240 V option in the 3‑pole Q-series lineup, making it the appropriate choice for safeguarding balanced 3‑phase equipment on circuits requiring 20 A per leg.
