Dual thermostat

ZR 011

Thermostat contact breaker (NC, normally closed) and thermostat normally open contact (NO, normally closed) in one casing. Unlike thermostats with change-over contact, the double thermostat switches independently. This allows heating and cooling devices to be switched in different temperature ranges.

Contact breaker (NC, heating) and normally open contact (NO, cooling) in one casing
Jump contact enables independent switching
Temperatures separately adjustable
High switching capacity
Clip fixing

Note	CSA approved 01176.0-00 and 01176.0-01 for controlling heat exchangers and fans (e.g. LE 019) and as an alarm or signaling contact for monitoring the internal temperature of the control cabinet. Wire end ferrules must be used for connections with stranded wires. The controller's contact system is exposed to environmental influences, which can change the contact resistance. This can lead to a voltage drop and/or self-heating of the contacts.
