The Siemens Q340 is a standard, 3-pole miniature thermal-magnetic circuit breaker from the Siemens QP/MP series, commonly used to protect 40 Amp, 3-phase circuits in load centers and panelboards. It is characterized by its common trip feature for simultaneous protection across all phases.
Features
-
Thermal-Magnetic Protection: Provides both long-time (overload) and instantaneous (short-circuit) trip functions.
-
Plug-In Design: Enables easy and fast installation in compatible Siemens enclosures.
-
Insta-Wire Feature: Simplifies terminal wiring, accommodating 8-6 AWG copper or 8-4 AWG aluminum wire.
-
Common Trip: All three poles trip simultaneously to ensure complete circuit disconnection during a fault condition.
- HACR Rated: Suitable for heating, air conditioning, and refrigeration applications.
