SW300-1044M 12V 300A Magnetically Latched Contactor - Intermittent

 Albright International SW300-1044M 12 Volts DC SPST magnetically latched 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.
• Magnetically latched contactor with extended armature and a Black operating knob.
• Yellow warning label fitted.
• Due to their configuration, the SW300 contactors are deemed non-serviceable; therefore, contact kits are unavailable.

Dimensions

• Height excluding black knob and armature extension, but including terminals and coil base cap: 79mm.
• Coil width: 40mm.
• Cap width: 49mm.
• Cap and fixed contact total width: 124mm.
• Fixed contact depth: 50mm.

Associated Parts

• 2070-40 Vertical mounting bracket single (2 x recommended)
• 2070-447 Horizontal mounting bracket kit (1 x recommended)

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.

 Magnetic Latching: The contact position is secured with the use of a permanent magnet within the assembly. The coil requires a pulse to close the contacts and a reverse polarity pulse to operate the armature and open the contacts, but otherwise remains in the last energised state without the need for power. It should be noted therefore, these are not failsafe.
