DC182B-687 Albright 24V DC Motor-reversing Solenoid Contactor - Prolonged

 Albright's DC182B-687 24 Volts DC motor-reversing solenoid contactor with magnetic blowouts, prolonged (PO).

• 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.

Magnetic Blowouts

 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 Prolonged (PO) DC182B Motor Reversing Solenoid

p> Prolonged (PO) use, up to 90% duty cycle and up to 54 minutes of continuous energisation. The coil is more powerful than continuous and weaker than the intermittent equivalent. The return spring is stronger than continuous but weaker than intermittent.

 The DC182 is a monoblock construction, resulting in a neat compact design that 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: 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).
