Albright SW204A-298 two24Vdc 250 Amps single-acting contactors on a steel bracket, with auxiliary microswitches and terminal board, continuous.
- 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 the right-hand contactor.
- Coils are wired in series.
- Two straight links connect main terminals in parallel.
Magnetic Blowouts
The contactors are double-break and 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. The 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, hardwearing and have excellent conductivity. The SW204 has M10 stud main terminals and a flying lead coil connection. Mounting can be horizontal or vertical, when vertical the M10 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). |
