Ratings

Rated load	Non-inductive		Inductive
Rated load	Resistive load	Lamp load	Inductive load	Motor load
250 VAC	20A	10A	8A	8A

Note:	1.	The non-inductive lamp load has an inrush current 10 times steady current.
	2.	The inductive load has a power factor of 0.4 minimum (AC).
	3.	The motor load has an inrush current 6 times steady current. The above ratings were tested under the following conditions: 1. Ambient temperature: 20±2 °C 2. Ambient humidity: 65±5 %RH 3. Switching frequency: 7 times/min.

Reset Coil

Rated voltage (operating voltage range)	Reset voltage (coil temperature: 20°C±2°C)	Rated energized current (coil temperature: 20°C±2°C)	Coil resistance (coil temperature: 20°C±2°C)	Permissible voltage applied period
24 VDC±10% (21.6 to 26.4 VDC)	21.6 V max.	185 mA±20%	130 Ω±20%	100 ms for min 1 s max.

Note:	1.	Current must not flow for more than 10 s, otherwise the performance of the coil may be affected.
	2.	If a semiconductor element is used to control the reset coil, the residual voltage caused by leakage current must be 2.4 VDC max.
