11B125024220 - 3P CONTACTOR B1250.24 220/240
MPN: 11B125024220
Alt. SKU: B125024220
Why Choose the 11B125024220?
Engineered for high-current switching, the Lovato B1250 three‑pole contactor delivers an IEC operating current Ith (AC1) of 1250 A with a 220–240 VAC 50/60 Hz AC coil. Built‑in 2NO+4NC auxiliary contacts support flexible signalling and interlocks, while screw mounting ensures a secure installation. With a rated insulation voltage Ui of 690 V and 8 kV impulse withstand, it provides robust performance in power distribution and industrial control applications.
Designed to endure, the B1250 offers a mechanical life of 5,000,000 cycles and operates from −50 to +60 °C, with storage from −60 to +80 °C and use up to 3000 m altitude (pollution degree 3). Terminal tightening torque is 35 Nm, and the unit weighs 4820 g. Conformity to IEC/EN 60947-1/-4-1, UL and CSA standards underpins safety and reliability across demanding installations.
