EJB14020 - 20 Amp Circuit Breaker

EJB14020 - 20 Amp Circuit Breaker

If you’re searching for a dependable circuit breaker that delivers steady overload and short‑circuit protection in demanding electrical systems, the EJB14020 is an excellent choice. This single‑pole, 20‑amp breaker operates at 277 VAC and is built to protect commercial and industrial circuits with confidence. Designed to mount securely in panelboards using a bolt-on method, it integrates smoothly into compatible systems — making installation easier and wiring safer. With its high interrupting rating and clean design, the EJB14020 helps ensure that your electrical setup runs smoothly and reliably, even under heavy loads or fault conditions.

Key Features and Benefits

• High Interrupting Capacity: With a 100 kA interrupting rating at 120 VAC (and 65 kA at 240/277 VAC), this breaker is engineered to handle severe fault currents — protecting equipment and wiring from damage.
• Thermal‑Magnetic Trip Unit: Combines overload protection (thermal) with short‑circuit protection (magnetic) for precise and dependable response — covering a wide range of potential electrical faults.
• Switching Duty Rated: Certified for switching duty applications, giving you flexibility for different types of loads and circuits.
• HID and HACR Rated: Meets requirements for high‑intensity discharge lighting and HVAC/refrigeration (HACR) equipment — great for lighting panels, HVAC control, and industrial load centers.
• Clear Trip Indicator: A visible indicator signals whenever the breaker has tripped, simplifying maintenance and troubleshooting so you can quickly spot issues without opening the panel.
