Electrically held

Electrically held contactors - Class LE

These Contactors are used in applications where it is not critical that the contacts remain in the closed position during loss of control power. Simplicity and compact lightweight design makes these contactors an attractive solution to your budgeting challenges.

Features & Benefits:

Contacts are rated 20 - 400 amps at 600 volts
3 and 4 pole (up to 12 pole for 30 and 60 amp contactors)
Most contactors have built-in auxiliary contacts for convenient 3-wire control
Wide range of coil voltages from 24 to 600 VAC 50/60Hz
Full line of enclosures including NEMA 1, 3/3R, 4, 4/4X stainless steel and 12

Electrically held

Electrically held lighting contactors - Class LC

This class of lighting contactors deliver unprecedented versatility in application, simplicity in configuration and performance in operation. Ingenious design, rugged construction, and a host of truly useful features make them uniquely appealing.

Features & Benefits:

Convenient side access field power wiring
A simple kit easily converts electrically held units to mechanically held and includes a 2- or 3-wire control module
Contact position indication – when button protrudes, contact is closed
Power poles can easily be added at any time based on changing needs. Furthermore, they may be converted from NO to NC (or vice versa) simply by repositioning

Mechanically held

Mechanically held contactors - Class CLM & CM

Siemens Class CLM & CM magnetically and mechanically held lighting contactors are used in applications where it is critical that the contacts remain in the closed position during loss of control power. These contactors do not change state and disconnect power from the load during a loss of control power whether momentary or sustained. That is because the operating coil is not required to be continuously energized. Since the coil is not continuously energized, energy is saved and coil hum is eliminated. This makes the contactor also ideal for applications where quite operation is critical.

Features & Benefits:

Rated for tungsten lighting (incandescent lament), ballast lighting (fluorescent, HID, metal halide, mercury vapor, quartz halogen and sodium-lamp), resistive and general use loads

Contacts are rated 20 - 400 amps at 600 volts
2 - 12 pole configurations depending on contactor size
Wide range of coil voltages from 24 to 600 VAC 50/60Hz
Full line of enclosures including NEMA 1, 3/3R, 4, 4/4X stainless steel and 12
Class CM includes disconnect and short-circuit protection and is UL rated as Service Entrance Equipment
