Dual thermostat

ZR 011

A thermostat with a normally closed (NC) contact and a normally open (NO) contact in a single casing. Unlike thermostats with a changeover contact, this dual thermostat operates independently. This allows heating devices and cooling devices to be switched within different temperature ranges.

Normally closed contact (NC, heating) and normally open contact (NO, cooling) in one casing
Snap-action contact enables independent switching
Temperatures can be set separately
High switching capacity
Clip mounting

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.
