## **Product De scri tion p** 

zero output power whilst 20 mA or 10 VDC correspond to full output power (near linear power response). The relay switches off every time the output cur rent cross es zero, and switches ON in ac cord ance with the ap plied control input. 

The analog switching relay works in accordance with  the phase angle control prin ci ple, i.e., the output switching point in the AC sine wave depends on the control input which can be either 4-20 mA or 0-10 VDC. 4 mA or 0 VDC correspond to

Notes: 

- Use of AC solid state relays may, according to the application and the load current, cause conducted radio interferences. Use of mains filters may be necessary for cases where the user must meet E.M.C requirements. The capacitor values given inside the filtering specification tables should be taken only as indications, the filter attenuation will depend on the final application. 

- The manufacturer has set the maximum allowable deviation under the influence of RFI to +/- 1.0% FSD or +/-1 step in distributed modes. 

- 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 65,000 Arms Symmetrical Amperes, 600 Volts maximum when protected by fuses. Tests at 65,000 A were performed with Class J, fast acting: please refer to the table below for maximum allowed ampere rating of the fuse. Use fuses only.
