High continuous current ratings in compact, rugged packages. Coils available to your specification anywhere in the range of 6 to 240 volts DC. An additional bridge rectifier enables using coils with AC power.

Silver-plated busbars on 600-amp and higher models prevent oxidation and eliminate the need to prepare connectors for installation.

Weld-resistant, hard-wearing silver alloy contact tips for excellent conductivity and long life. Double breaking design protects against arcing.

Easy to install, and fully field serviceable with genuine Curtis/Albright parts.

Auxiliary contacts. A set of auxiliary contacts (one normally open, one normally closed) mechanically linked to the main contacts.

Magnetic blowouts.Protects against sustained arcs; recommended at 48 volts DC and higher.

Coils for continuous operation.Allow continuous energization of the coil, compared with standard coils rated for intermittent operation (ON time under 70 percent and less than 15 minutes).

Mounting brackets.A wide selection of standard brackets for easy installation anywhere; customized brackets and hardware for special applications are available.

Coil suppression.Diode suppresses voltage spikes when coil is de-energized. Because this slows the contacts drop-out time, resistor/diode combinations are available to minimize this effect.

Enclosed top cover.Protects contacts from dust and other contaminants (not recommended with use of magnetic blowouts).

AC operated coil.DC coil fitted with bridge rectifier for use with AC power.

Large diameter contact tips.Increased surface area minimizes contact corrosion from high switching frequencies.

Lockable mechanism.A manual disconnect switch that – once engaged to the OFF position – can only be rearmed with the supervisor's key.

Metal enclosed contactors.Available for industrial vehicle applications requiring UL-EE rating.
