SIR852160-WJ

celpac® New Solid State Relay compact size pitch 22,5mm with spring terminals t Ready to use Single-Phase Relay: " Install it & Forget it!" t Zero cross model : 12-440VAC 25A(*) alternistor on output. I2t value > 312A2s . t Quick connection : Spring terminals ( 2,5mm2 : 16A max) t Specially design for AC-51 resistive loads t 4-30VDC control with LED t IP20 housing t Low leakage current (12AWG) L = 6mm Mounting Warning : only in vertical position. The user should protect heat sensitive materials as well as persons against any contacts with the heatsink. For non vertical mounting , the load current must be 50% lower than the rated one . For a good cooling, the SSR needs an air convection. Less convection air produces an abnormal heating. Keep a distance between the upper SSR and the lower SSR. In case of no space between two SSR ( zero space between two SSRs) , please reduce the load current. For further details refer to below : Ø Ø Derating current with no space between SSRs AC-51 nominal currents are given with a space of 22,5mm between each SSR, for a permanent current during a minimum time of 8 hours in air calm according to IEC60947-4-3. In case of non permanent currents or in case of SSRs are mounted with no space, you must check the heatsink temperature never exceed 90°C. When the SSRs are mounted side to side ( no space between each relay) a derating current of 25% must be take into account. A forced cooling ( fan inside the cabinet) improves significantly the thermal performances. vertical position 80mm Typical application : LOADS LOADS This SIR product is designed mainly for AC-51 résistive load. Protection : To protect the SSR against a short-circuit of the load , use a fuse with a I2t value = 1/2 I2t value specified page 2. A test has been made with FERRAZ fuse ( see page 2). It is possible to protect SSR by MCB ( miniature circuit breaker). In this case, see application note ( SSR protection) and use a SSR with high I2t value (5000A2s minimum) EMC : Ø Immunity : We give in our data-sheets, the immunity level of our SSRs according to the main standards for this type of products : EN61000-4-4 &5. You can see the high immunity level in comparison with the products on the market. Ø Emission: SSRs are complex devices which must be interconnected with other equipment (loads, cables,etc.) to form a system. Because the other equipment or the interconnections may not be under the control of celduc, it shall be the responsibility of the system integrator to ensure that systems containing SSRs comply with the requirements of any rules and regulations applicable at the system level.
