FH26020AC - 20 Amp Circuit Breaker

FH26020AC - 20 Amp Circuit Breaker

Upgrade your electrical system’s protection with the FH26020AC from Schneider Electric’s I-Line family. This two-pole, 20-amp thermal-magnetic circuit breaker is rated for 600 V AC and is engineered to guard against both long-term overloads and sudden short-circuit events. The dual protection mechanism ensures dependable performance, whether your application is running continuously or experiencing large fault currents. Thanks to its I-Line mounting configuration, installation is streamlined and maintenance-friendly—so you spend less time in the electrical room and more time running your system reliably. With superior interrupting ability and compliance to stringent safety and environmental standards, this breaker is a substantial addition to industrial and commercial electrical setups.

Key Features and Benefits

• Thermal-Magnetic Trip Unit: Combines long-time overload protection with instantaneous short-circuit response to help safeguard wiring and equipment from damage.
• High Interrupting Capacity (Breaking Capacity Code H): Built to handle high fault currents—delivering up to 18 kA at 600 V AC (65 kA at 240 V AC) for added confidence in demanding environments.
• I-Line Mounting Mode: Engineered for efficient, plug-in I-Line installation—facilitating faster wiring, reduced downtime, and simpler maintenance access.
• Dual-Pole Design: With two poles, this breaker is ideal for controlling circuits that require simultaneous disconnect of two conductors—typical in multi-phase and 240 V branch circuits.
• Clear Load & Line Connections: Features lugs for load and I-Line connection for line, making connections straightforward and secure.
