Albright SW204A-298 two single acting 24V contactor on a steel bracket, with auxiliary microswitches and terminal board.
- The SW204 has been designed for direct current loads, including motors as used on electric vehicles such as industrial trucks. Developed for both interrupted and uninterrupted loads, the SW204 is suitable for switching Resistive, Capacitive and Inductive loads.
- The contactors are compact in size and are fully serviceable, with a range of spare parts available.
- Repair contact kit part number: 2155-99 (2 required)
- Auxiliary switch kit part number: 2155-202 (2 required)
- Vacuum impregnated coil windings.
- Terminal board on right hand contactor.
- Coils wired in series.
- Two straight links connecting main terminals in parallel.
Magnetic Blowouts
The contactors are of double break configuration and are fitted with magnetic blowouts across both contact gaps as standard. These enable high currents to be ruptured very quickly so that arcing time is reduced to a minimum. Fitting of blowouts makes the contacts polarity sensitive and the positive markings on the top cover of the contactor must be observed.
About Continuous (CO.) SW204 Solenoids
Continuous contactors by design are predominantly used for drive functions on vehicles, they make and break slower than intermittent solenoids and are recommended for prolonged contact periods.
The SW204 has been designed for direct current loads, including motors as used on electric vehicles such as industrial trucks. Developed for both interrupted and uninterrupted loads, the SW204 is suitable for switching Resistive, Capacitive and Inductive loads.
The SW204 features 2 x single pole single throw, double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. The SW204 has M10 stud main terminals and flying lead coil connection. Mounting can be horizontal or vertical, when vertical the M10 contact studs should point upwards.
| Interrupted current - opening and closing on load with frequent switching (results in increased contact resistance). |
| Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance). |
