FAQ

Question?

What is the difference between the GV2-RT and GV2-ME series?

The GV2-RT series, like this GV2-RT21, uses a rotary knob for operation and features EverLink BTR screw clamp terminals designed for a permanent and reliable connection. The GV2-ME series typically uses push buttons for operation and standard screw clamp terminals.

Can I add auxiliary contacts to this GV2-RT21 circuit breaker?

Yes, the TeSys GV2 series is modular. You can add front-mounted (GVAN) or side-mounted (GVAD, GVAE) auxiliary contact blocks to provide additional signaling contacts for your control circuit. This unit already appears to have built-in auxiliary contacts (1 NO + 1 NC).

What does the 'thermal-magnetic' trip technology mean for this device?

'Thermal-magnetic' refers to the two types of protection it offers. The thermal protection (adjustable 17-23A dial) uses a bimetallic strip to trip on sustained overcurrents (motor overload). The magnetic protection is non-adjustable and trips instantaneously on high short-circuit currents to prevent severe damage.
