Product Description

SW88 48V DC industrial contactor/DP contactor

SW88 48V DC industrial contactor/DP contactor

The SW88 series of contactors has been designed for direct current loads, particularly motors as used on small electric vehicles such as light industrial trucks, powered invalid cars, etc.

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

The SW88 main contact circuit, designed for motor reversing, is such that it has a built in failsafe, so that if both coils are energised simultaneously the contact arrangement is open circuits.

They are economical in price and compare favourably with sealed automotive style solenoid switches which cannot be serviced or inspected for contact wear.

Compact Size: The contactors are compact in size and are fully serviceable with a full range of spare parts available.

Installation: Mounting is via the supplied mounting bracket.

Magnetic Blowouts: Fitting of magnetic blowouts make the polarity sensitive and the positive markings on the top cover of the contactor must be observed. Suffix 'B' denotes the fitting of magnetic blowouts.

Auxiliary Contact: Denoted by 'A', a double circuit normally open, normally closed microswitch auxiliary contact can be fitted, ratings as shown below.
