FEATURES
- Sealed with an inert gas, ensuring freedom from aging and influences exerted by external environment.
- The twin contact and wiping effect assures outstanding contact reliability, probability of failure is extremely low.
- Quick action permits a larger make and break capacity and longer service life.
- Can switch both AC and DC, permitting direct control over a wide range from low level load to electromagnetic power load.
Medium-capacity type : 5V 1mA to 240VAC 0.5A (5A making)
NEMA Contact Ratings : C300 (AC) and Q150 (DC)
NEMA HP Ratings : 1/10HP (120Vac), 1/8HP (240Vac)
- Small surge/noise during switching of inductive load.
UL RECOGNIZED IN ACCORDANCE WITH USA AND CANADIAN STANDARDS File No. E159361

1 Where 240VAC, the rated operational current is set at 10 times this value upon making (PF: 0.6 to 0.7) and 1 times this value upon breaking (PF 0.3 to 0.4). Rated operational current 1A means 10A making and 1A breaking.
2 Where 115VDC is indicated, the current is set at 1 times making and 1 times breaking.
3 The maximum making current complies with JIS C 4531, and enables 100 times making at a power factor of PF: 0.7.
4 The maximum breaking current, by referring to JIS C 4531, is based on switching 25 times at PF: 0.4 (AC) cases for the large capacity element. For the medium capacity element, switching 25 times at PF: 0.4 (AC) case only.
5 The maximum breaking current, by referring to JIS C 4531, is based on switching 25 times at time constant t = 100ms (DC) for either 115/230VDC cases for the large capacity element. For the medium capacity element, switching 25 times at time constant t = 40ms for 115VDC case only.
6 Where 24V 1mA is in circuit with optcoupler, 5V 10mA can be used.
