Description

Ideal for use in systems requiring limited interrupting capacity, such as adjustable speed drives, transit and rail, gas and oil well drilling equipment, fuel cells, and crane controls.  When used to replace a circuit breaker in a high-current DC application better suited to a contactor, the Type 703 is valued for its smaller size, lower cost, and longer life.  This single pole, single throw normally open power contactor is rated at 5000 Ampere continuous duty at 1000 VDC in still air, with a maximum interrupting capactiy of 4000 kW (within the limits of 5000 Ampere maximum and 1000 V maximum) and utilizing a polarized arc interruption system.

Features:

• Multiple-path silver alloy main contacts
• Arc chute safety interlock
• Silver-plated current-carrying connections
• Dual coil operation
• High dielectric and mechanical strength
• Permanent magnet (polarized) arc chute
