Trombetta PowerSeal 12V / 24V / 48V DC Contactor

Intermittent Duty, Non-Grounded

Overview

The TROMBETTA 684-1261 / 684-2461 / 684-4861 contactor is designed for direct current loads, particularly for motors on small electric vehicles such as light industrial trucks, electric forklift, electric pallet stacker, golf cart, etc. For automotive, the typical application of TROMBETTA contactors 684-1261 / 684-2461 / 684-4861, is engine starter DC relay.

TROMBETTA has double breaking main contacts with silver alloy contact tips, which are weld resistant, hard wearing and have excellent conductivity.

TROMBETTA PowerSeal 684-1261 / 684-2461 / 684-4861 are contactors of unicoil winding, with curved "L" shape bracket. We supply also similar contactor with flat type "L" shape bracket, model 684-2451-212-17 (24V).
