1.Economic pricing that promptly reflects market demands

Remarkable economic pricing is implemented in pursuit of cost performance.


2.Output contacts switchable between timed out 2C and timed out 1C/Instantaneous 1C

The timed out 1C/Instantaneous 1C output contact enables the efficient addition of self-maintenance circuits.


3.4 different time ranges selectable on a single unit

Five types of timers cover the full range of time settings from 1 second to 30 hours.


4.Equipped with zero-setting instantaneous output

Set the dial all the way to “0” for instantaneous operation, so circuit testing can be easily accomplished.


5.Compliant with UL, c-UL and CE.
