Albright's DC182B-604, 72-80 volt dc intermittent use, motor reversing solenoid contactor with magnetic blowouts.
- The DC182B series of contactors has been designed for direct current loads, particularly motors as used on electric vehicles such as industrial trucks, airport tractors, and such like.
- They have double breaking main contacts with silver alloy contact tips, which are weld resistant, hardwearing and have excellent conductivity.
- The DC182 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.
- 2159-39 Albright DC182 Solenoid Mounting Bracket.
- 2155-165 Albright Large Solenoid L-Shape Mounting Bracket (requires 2x)
These contactors are fitted with magnetic blowouts (denoted by 'B' suffix in the DC182B range) across contact gaps. These enable high currents to be ruptured very quickly so that arcing time is reduced to a minimum. Fitting of blowouts can make the contacts polarity sensitive and the positive markings on the top cover of the contactor must be observed.
About the DC182B-604 Motor Reversing Solenoid
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 DC182 is a monoblock construction, resulting in a neat compact design which is compatible with modern electronic control systems. The DC182 is physically and electrically interchangeable with the SW182 reversing contactor but rewiring will be required.
This version of the DC182 has M8 stud main terminals and 6.3mm spade coil connections. Mounted using brackets available separately via the M5 mounting holes (16 off, 8 per side), mounting of the solenoids can be horizontal or vertical, when vertical the M8 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). |
