Albright International SW300-1020 30 Volts single-pole, single-throw (SPST) solenoid contactor, intermittent.

The SW300 is designed for use in telecommunications and power distribution applications where an uninterrupted current load is switched.
These contactors are primarily used with Direct Current loads but can also be used with Alternating Currents.
The SW300 features double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity.
Non-silver plated fixed contacts fitted.
Due to their configuration, the SW300 contactors are deemed non-serviceable; therefore, contact kits are unavailable.

Dimensions

Height including terminals and coil base cap: 79mm.
Coil width: 40mm.
Cap width: 49mm.
Cap and fixed contact total width: 124mm.
Fixed contact depth: 50mm.

About Intermittent (INT.) SW300 Solenoids

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 SW300 is a compact contactor that can be busbar mounted vertically or horizontally. If mounted vertically, the coil should be at the bottom.

Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance).
