Frequently Asked Questions for HQ55C1
ESBEE HQ55C1 is a 22.5 mm industrial push button / actuator engineered specifically for Indian LT switchboards, control desks, and motor starters. Rated for voltages up to 415V AC (50 Hz) and 10A thermal current (Ith), it complies with IS/IEC 60947-5-1 (AC-15: 4A at 240V, 2A at 415V).
Featuring a precision neoprene sealing ring, HQ55C1 delivers IP65 ingress protection compliant with IS/IEC 60529, effectively preventing the ingress of water splashes, moisture, coal/cement dust, and industrial lubricants common in Indian manufacturing plants.
The HQ55C1 accommodates modular clip-on contact blocks (1NO, 1NC, 1NO+1NC, 2NO, or 2NC) with silver alloy contacts. The NC contact elements feature positive opening action for reliable emergency stop tripping compliant with Indian factory safety norms.
Designed for over 3 million mechanical switching cycles, HQ55C1 mounts into standard 22.5 mm panel punch-outs with an anti-rotation locating lug and a sturdy rear locking ring that prevents loosening during heavy shift operations.
Source genuine ESBEE HQ55C1 push buttons on Electrihub India. Electrihub India supplies factory-original products, competitive wholesale prices, valid 18% GST tax invoices for Input Tax Credit (ITC), and rapid door-step delivery Pan-India.
The ESBEE HQ55C1 belongs to the ESBEE 22 mm industrial pushbutton range, and it installs into the global-standard 22 mm round panel cutout defined in IEC 60947-1, so it fits the same enclosure hole as other 22 mm branded pushbuttons. Checking this cutout size before ordering avoids rework on an already-drilled control panel, and because the dimension follows an internationally recognised standard, panels designed in one country can be fitted with the HQ55C1 sourced from another without modifying the enclosure.
The ESBEE HQ55C1 is rated at IP65 protection as a fully assembled unit, giving dust and low-pressure-jet water resistance for factory and control-panel environments. This level of sealing is what determines whether the device can be specified for washdown areas, outdoor enclosures, dusty workshops or humid coastal sites, so it is one of the first specifications engineers in any country check when matching a pushbutton to its installation environment.
The ESBEE HQ55C1 is manufactured to IS/IEC 60947-5-1 and IEC 60947-1 with CE marking on export batches, making it usable both on domestic Indian panels and on equipment shipped to IEC-regulated export markets. Holding recognised IEC, UL, CSA and CE approvals together (rather than just one regional mark) is what lets the same part number be specified on machinery and switchgear panels built for the EU, North America, the Middle East, Africa and Asia-Pacific, without needing a region-specific substitute.
The ESBEE HQ55C1 offers a rated insulation voltage of up to 415 V AC and a rated thermal current of around 6 A, available with 1 NO, 1 NC or 1 NO+1 NC contact blocks and screw terminals. Confirming the rated voltage, current and contact configuration against the control circuit it will switch is essential, since undersizing the contact block against the connected load is one of the most common causes of premature pushbutton failure in the field.
The ESBEE HQ55C1 is rated for an operating range of -5°C to +55°C, matched to hot/humid tropical climates as well as more temperate installation sites, with a mechanical durability rated for several hundred thousand operating cycles in normal industrial duty. This combination of climate range and cycle life is what allows the same push button to be deployed in cold-storage plants, standard factory floors and hot, humid outdoor installations across different climate zones without a separate temperature-rated variant.
