TH-T Series Features

Applicable to motor protection: can be used for standard motor overload and locking protection.
Easy current value setting: can directly set the motor current value. Adjust with a cross-head / straight-slot screwdriver.
Reset method change: easy to change between manual reset and automatic reset.
With 1a1b contact: can use different voltages for a and b contacts.
Terminal cover as standard equipment (TH-T18/TH-T50): Having a terminal cover as standard equipment reduces the time for customers to specify a separate model name or arrange for options. This reduces inventory and reduces cover costs. Safety has also improved for protecting the live parts.
