Description
Himel HDC19S11512M7 Capacitor Switching Contactor
The **Himel HDC19S11512M7** is a three-pole capacitor-duty contactor from the HDC19s series. It is designed for switching capacitor banks in power factor correction installations, helping electrical systems compensate for reactive power and improve power factor when correctly sized and configured.
Unlike a standard-purpose contactor, a capacitor switching contactor is designed to address the high inrush current that can occur when capacitors are energized. The HDC19s series incorporates technology intended to reduce the impact of capacitor closing current on the contactor contacts.

Features and Benefits
Designed for Capacitor Switching
The HDC19s series is specifically developed for capacitor switching in power factor correction systems. Its design helps reduce the impact of capacitor inrush current on the contactor contacts.
Three-Pole Switching
The three-pole configuration supports suitable three-phase capacitor bank installations when the electrical ratings and system design are compatible.
220/230V AC Control Coil
The control coil operates at 220/230V AC and 50/60Hz. Verify the control supply and complete model code before ordering or installation.
Integrated Auxiliary Contacts
The 1 NO + 2 NC auxiliary contact arrangement supports control, indication and interlocking circuits where required by the system design.
Industrial Electrical Panel Applications
The HDC19s series is intended for power factor correction equipment and capacitor compensation control cabinets. The enclosure and installation must provide the required protection because the product is rated IP20.
Typical Applications
The Himel HDC19S11512M7 may be considered for appropriately engineered installations such as:
– Automatic power factor correction panels
– Three-phase capacitor banks
– Reactive power compensation systems
– Industrial electrical distribution panels
– Commercial power factor correction installations
– Capacitor bank control and switching assemblies
Final selection depends on the capacitor-bank rating, operating voltage, switching duty, harmonics and the protection and control equipment used.
Selection and Installation Guidance
Before purchasing or installing this contactor:
1. **Confirm the coil voltage:** The specified control coil is 220/230V AC, 50/60Hz.
2. **Check the capacitor-bank rating:** Use the manufacturer’s AC-6b capacitor current and kVAr ratings at the intended operating voltage rather than relying on the 115A thermal current rating alone.
3. **Assess inrush current and harmonics:** Verify suitability for the system’s capacitor switching conditions, including any detuned reactors or harmonic concerns.
4. **Confirm auxiliary contacts:** Ensure the 1 NO + 2 NC arrangement suits the control circuit.
5. **Check protection and enclosure requirements:** IP20 equipment requires suitable installation protection against accidental contact and environmental exposure.
Installation and commissioning should be carried out by a qualified electrical professional using the manufacturer’s documentation.
