Albright SW181B-141 24V DC CO - Continuous
CO-type (Continuous) can be run always on
Magnetic Blowouts
These contactors are fitted with magnetic blowouts - denoted by 'B' suffix in the SW181B 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.
This SW181B-141 is also used in Haulotte machines under code 2440318890 - Contactor 24V Albright SW181B-141
Haulotte 2440318890 Contactor 24V, fits Haulotte HA15IP / HA43JE / HA12IP / HA33JE
About SW181B-141 Solenoids
Continuous contactors by design are predominantly for drive functions on vehicles, they have weaker coils, switch slightly slower than intermittent solenoids and are recommended for prolonged contact periods.
The SW181 has M8 stud main terminals and 6.3mm spade coil connections. It can be mounted via M5 tapped holes or mounting brackets purchased as separate items. Mounting can be horizontal or vertical, when vertical the M8 contact studs should point upwards. Please note Normally Closed contacts are not suited to make and break load.
| 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). |
