SIRIUS 3RV1341-4KC10 — circuit breaker for starter combinations
It carries a 690 V rated value and is rated for AC-3 duty up to 690 V, so it covers 400 V and 480 V systems with headroom. The 38 W power dissipation at rated load matters for thermal management inside a packed enclosure; that's about 12.7 W per pole.
The 70 mm width, 165 mm height, and 174 mm depth fit a standard modular panel footprint; zero clearance required at the sides or rear means it can sit tight against adjacent devices without derating for airflow. Any mounting position is permitted. Finger-safe touch protection per the spec reduces arc-flash risk during maintenance.
Main current circuit uses screw-type box terminals. Solid conductors: 2x (2.5…16 mm²). Stranded: 2x (10…50 mm²) or 1x (10…70 mm²). Finely stranded with ferrule: 2x (2.5…35 mm²) or 2.5…50 mm². AWG equivalents for main contacts: 2x (10…1) or 1x (10…2). Auxiliary and control circuit terminals are also screw-type. The wire ranges cover typical motor power cables up to 70 mm² — no need for lug adaptors on most installations.
RoHS compliance date listed as July 1, 2006, covering the EU RoHS directive. Shock resistance rated at 25g for 11 ms. Surge voltage resistance rated at 6 kV. No ground fault detection or phase failure detection built in — those functions, if needed, must come from an upstream device or an add-on module. An auxiliary switch can be added via the product extension option.
