About The Intermittent SW88-117 Reversing Contactors
Intermittent contactors, by design, are predominantly used for hydraulic functions on vehicles; they make and break quicker than continuous solenoids and are not recommended for prolonged contact periods.
The SW88 is a configuration of two SW84-type contactors on a common bracket for motor reversing. The SW88 features single pole double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing 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.
The SW88 has M8 stud main terminals and flying lead coil connections. Mounted mag-frame M4 tapped holes, mounting of the solenoids can be horizontal or vertical. When vertical, the M8 contact studs should point upwards.
Interrupted Current: The opening and closing on load with frequent switching (resulting in increased contact resistance). |
Uninterrupted Current: No or infrequent load switching requirements (maintains a lower contact resistance). |
