Tomzn AC Breaker 63amps

Key Technical Specifications

Rated Current ($I_n$): 60A or 63A (The 63A model is the standard manufacturing size used for 60A requirements).

Rated Voltage (2$U_e$): Typically rated for 500V DC (1-pole) or up to 1000V DC (2-pole).3

Breaking Capacity: 6kA (6000 Amps), which refers to the maximum fault current the breaker can safely interrupt.

Tripping Curve: C-Curve (Standard for solar/inductive loads, trips at 5–10x rated current).4

Mounting: Standard 35mm DIN rail.5

Poles: Usually available in 2P (Double Pole) configuration for solar applications to isolate both the positive and negative lines.6

Primary Applications

Solar PV Systems: Used between the solar panel arrays and the charge controller or inverter to protect against overcurrent and short circuits.7

Battery Protection: Ideal for protecting deep-cycle battery banks in off-grid setups.8

Electric Vehicles (EV): Sometimes used in low-voltage DC charging or internal circuitry.

Telecommunications: Used to safeguard DC-powered communication equipment.9

Important Features

Arc Extinguishing: DC current does not have a "zero-crossing" like AC, meaning arcs are much harder to put out. This breaker features internal magnetic arc runners to pull the arc away from the contacts and extinguish it quickly.

Non-Polarity: Many modern TOMZN models are "non-polarized," meaning you can wire the input/output from either the top or bottom without worrying about + or - orientation (though always check the specific wiring diagram on your unit's faceplate).

Visual Status: Includes a clear Red/Green indicator to show if the circuit is Closed (On) or Open (Off/Tripped).
