HGL36020 - 20 Amp Circuit Breaker

HGL36020 - 20 Amp Circuit Breaker

When you’re specifying protection for critical electrical systems in commercial or industrial environments, the HGL36020 20 Amp 3-pole circuit breaker delivers dependable performance and smart design – engineered to safeguard your equipment and give you confidence in the field. This unit, from the PowerPacT H-Frame line by Schneider Electric, is rated for up to 600 VAC and offers an impressive 18 kA interrupting capacity at that voltage. It uses a thermal-magnetic trip unit that combines overload protection (thermal) with fast response to short-circuit conditions (magnetic). With dual-break rotating contacts, the design helps reduce peak current during fault events, which means less stress on your system and a longer lifespan for your installation. The push-to-trip button lets you test the breaker manually, ensuring your safety system is ready when you need it. Whether you’re managing large building services, industrial machinery, or infrastructure installations, the HGL36020 delivers the specification clarity and protection performance you need.

Key Features and Benefits

• 18 kA at 600 VAC breaking capacity: Handles high fault currents in heavy-duty applications, giving you peace of mind in demanding environments.
• Thermal-magnetic trip unit: Offers dual-mode protection — thermal for longer-term overloads and magnetic for instantaneous short-circuit events — so you get a comprehensive protective solution.
• Dual-break rotating contacts: These contacts reduce peak fault current, which lowers stress on conductors and connected equipment and helps extend service life.
• Push-to-trip button: Enables manual testing of the breaker function without needing external test equipment — a practical benefit for preventive maintenance or commissioning.
• Lug terminals with unit-mounting format: Simplifies installation and ensures secure, high-quality connections in control panels or switchboards.
