## **Product De scri tion p** 

The instant-on relay with DC control input can be used for phase control. The builtin varistor secures transient protection for the heavy industrial applications, and the LED indicates the status of the control input. The clip-on cover is securing touch protection  to IP 20. Protected output terminals can handle cables up to 16mm[2] . 

The industrial, 1-phase relay with antiparallel thyristor output is the most widely used indus trial SSR due to its multiple application possibilities. The relay can be used for resis tive, inductive and capacitive loads. The zero switching relay switches ON when the sinusoidal curve crosses zero and switches OFF when the current crosses zero.

Notes: 

- Control input lines must be installed together to maintain products’ susceptibility to Radio Frequency interference. 

- Performance Criteria 1: No degradation of performance or loss of function is allowed when the product is operated as intended. 

- Performance Criteria 2: During the test, degradation of performance or partial loss of function is allowed. However, when the test is complete the product 

should return operating as intended by itself. 

- Performance Criteria 3: Temporary loss of function is allowed, provided the function can be restored by manual operation of the controls.

## **Short Circuit Protection** 

Protection Co-ordination, Type 1 vs. Type 2: 

Type 1 protection implies that after a short circuit, the device under test will no longer be in a functioning state. In type 2     co-ordination the device under test will still be functional after the short circuit. In both cases, however, the short circuit has to be interrupted. The fuse between enclosure and supply shall not open. The door or cover of the enclosure shall not be blown open. There shall be no damage to conductors of terminals and the conductors shall not separate from terminals. Therese shall be no breakage or cracking of insulating bases to the extent that the integrity of the mounting of live parts is impaired. Discharge of parts or any risk of fire shall not occur. 

The product variants listed in the table hereunder are suitable for use on a circuit capable of delivering not more than 65,000A rms Symmetrical Amperes, 600Volts maximum when protected by fuses. Tests at 65,000A were performed with Class J, fast acting: please refer to the table below for maximum allowed ampere rating of the fuse. Use fuses only.
