Heschen Household AC Contactor, HSR1-63, 4 Pole Four Normally Closed, AC 220V/240V Coil Voltage, 35mm DIN Rail Mount

Funziona

El producto funciona correctamente pero en la primera medición que hice aparecía como que tenía un defecto, se debe a que llevan un barniz protector y que cuando mides con un tester entre los tornillos no mide continuidad pero haces la medición en el lugar donde entran los cables y funciona perfectamente, una persona que lo compro con anterioridad lo devolvió porque no me dio correctamente porque en los tornillos no sería la mejor forma aunque teóricamente debería de marcar la misma continuidad

Price is V. competitive for 63A/25kW resistive load and 4poles. For moderate reactive loads (motor) rating is 8kW or say 33A @ 240V which is also good. I bought this for automatic load sharing an EV charger and drier. (~resistive loads). It is CE marked but not UL marked, this can be an issue with local regulations in USA which may need UL. The plastic body has screwdriver metric torque settings embossed near clamps. This is important for safety to meet code and prevent overheating/arcing. (0.8N-M for excitation connection and 3.5N-M for main power connections.) Note the switching excitation requires ~240VAC it will not work with 120V. This is what I needed, but often control circuits are 120V not 240V. The contactor has a nice feature a small red flag that shows when contacts are closed. It also has an insulated slot in the side which can be used to temporarily manually operate the contactor for testing. Others have reported loose objects rattling inside if shaken. Mine was also like that. When I opened it carefully (4 plastic clips in base), I found there were 2 of 4 fragile round plastic holding pins broken off inside. I glued them back and reinforced all 4 round pins and the two H shaped pins with epoxy. The pins keep some rubber mounting dampers and the magnet assembly in correct place. This seems to be a weak point in an otherwise good design. My unit worked before and after reinforcing it but it required some skill to reassemble correctly. I could not find many Normally closed contactors on amazon at a reasonable price so it maybe worth getting this and being prepared to return it if it rattles. I am an electronics engineer so I was prepared to repair this but for the average user I can't recommend this. The fourth picture shows the two broken pins from my unit and the two unbroken pins and H shaped pins on the top plate. The fifth picture shows the magnetic assembly they hold in place when the top is mated to bottom. The H shaped pins on top plate press on the square rubber mounts on either side of the magnetic core.

Ich bin absolut zufrieden, weil ich genau das bekommen habe, was ich haben wollte, und es funktioniert, wie es funktionieren soll. Außerdem stimmen der Preis und die Qualität der Ware.
