Panel fit and switching capacity
The 3RH2140-1BE40 is a SIRIUS auxiliary contactor in size S00, carrying four normally-open instantaneous contacts.
Mounting flexibility and clearance
This allows installation in tight enclosures or on swing panels where the orientation is not perfectly plumb. These spacings ensure adequate arc-quenching and heat dissipation; crowding the contactor closer than these values may reduce the switching capacity or cause nuisance tripping in a fault condition. The screw terminals are sized for control-circuit wiring typical in panel builds — no special crimp tools required.
Environmental tolerance and compliance
Relative humidity minimum is 10 %. The product carries a substance prohibitance date of 10/01/2009, aligning with RoHS and REACH compliance timelines. The auxiliary switch extension is supported — the contactor accepts add-on auxiliary contact blocks for field expansion. The magnet coil is designed for continuous duty.
