Be the first to Review this product. By using a voltage meter, you are able to test whether or not your contactors circuit is complete. The buyer has the option to exchange the item if we have another in stock, or for the purchase price. Typical Coil Codes and Voltages. Note: The contactor requires external control relays and a rectification circuit to control the standard DC closing and hold-in coils on the contactor. Contactors Terminal Blocks Circuit Breakers 800-262-IDEC (4332) • USA & Canada 989 Contactors 1705151136 YC1N(K) YC1N(K) Mini Contactors Part Number Key YC1 N - 5 B A120 Coil Voltage Code N: AC Coil K: DC Coil Contactor Size* (5, 6) *See selection table for details. : A 240V coil is required for an A75 contactor: A75-30-00-80 Coil voltage selection Cntr Volts. EATON Moeller Contactor DILM17-01 220V Coil Voltage, 3 Phase NC (XTCE018C01AO) $ 54. Rated voltage Coil voltage Gravitational force Contacts open Contacts closed Rated voltage Note: Since SC series contactors are electroni-cally controlled there is no unstable zone. The input impedance (A1-A2) of the electronic coil (110-125VDC) is dependent on the input voltage, on the pick-up or holding phase, and on the frame size of the contactor. 11 Coil Assembly: Energized part to make fixed core an electromagnet 12 Fixed Core: The part where it becomes an electromagnet when coil is energized. Contactors are used to remotely switch electrical power. : A 24V coil is required for an DA75 contactor: DA75-20-11-81 Additional auxiliary contacts. Contactors and relays are operated by applying a voltage to the coil of an Electro-magnet, which will cause a switch, (or several switches) to close. 150 - 200 Amp Rating, Coil Voltage 12 V to 240 VDC. 3: Switching overvoltage of a contactor relay magnetic coil 230 V, 50 Hz, 10 VA for an RC element circuit with 110 Ω, 0. Current flow through an AC coil is limited by both _____and _____. Small amount of power is used up by the contactor coil during its operation. Auxiliary Contact Units shows the maximum number of units that may be added to a given size contactor (in addition to the coil auxiliary contact). 95 Buy EATON Moeller Contactor DILM32-01 24V Coil Voltage, 3 Phase NC (XTCE032C01) $ 160. The coil voltage, or control voltage, is what actuates or enables your coil to operate the 3RT contactor. If the contactor coil is getting 24 volts and not engaging then you need a new contactor. I ran the system forc awhile after this a toggled between both heat and cool and everything seemed ok. Contact Amperage 20A, 30A, 50A, 75A, 100A, 125A, 150A, 225A, 350A. The coil is a crucial component of high-voltage contactors as it provides the driving force to close the contacts.
