TOMZN TOB1-63H 2P AC C-Type MCB is a 2-pole alternating current circuit breaker designed to protect electrical circuits from overload and short-circuit faults in lighting and motor distribution systems. It features a compact, lightweight and reliable design with a fire-resistant, shock-proof plastic body for long-lasting performance. The breaker is suitable for 230/400 V AC at 50/60 Hz systems and is widely used in residential, commercial, and industrial applications. The C-type trip curve makes it capable of handling moderate inrush currents, such as those from motors and fluorescent lighting, without unnecessary tripping.

2-Pole DC Surge Protection – Designed to protect DC power systems (e.g., solar PV strings and DC distribution) from damaging voltage surges and transient spikes.
High Discharge Capacity (20 kA ~ 40 kA) – Can absorb and divert large surge currents caused by lightning or fast transient overvoltage events, helping safeguard connected equipment.
Rated for Up to 1000 V DC – Suitable for high-voltage DC systems typically used in photovoltaic (solar) installations and other DC circuitry.
Fast Response Time – Activates quickly (in microseconds) to reduce exposure to harmful transient events in the DC network.
Low Residual Voltage – Limits the voltage that passes through to sensitive devices during a surge, minimizing potential damage
Thermal Disconnect Safety – Built-in thermal disconnect devices improve reliability by isolating the unit if internal components overheat.
Visual Status Indicators – Color-coded indicators (e.g., green for normal, red for fault) provide quick feedback on protection status.
DIN-Rail Mountable – Easy installation in DC combiner boxes, PV distribution panels, and electrical cabinets using standard DIN-rail mounting.
2P + 2P DC Manual Transfer Switch (MTS) – Lets you manually switch between two DC power sources in a photovoltaic (PV) setup, such as a solar array and a backup battery bank.
Dual Power Operation – Designed for DC dual power systems to ensure continuity of power without automatic switching.
Rated for High DC Voltage: Supports up to 1000 V DC, meeting common PV system requirements.
Integrated Circuit Breaker Protection: Combines manual transfer switching with overload and short‑circuit protection in one unit.
2P + 2P Pole Structure: Provides full protection and switching for two separate DC sources (each 2‑pole).
Rated Current Options: Available (commonly) at 63 A and potentially other ratings depending on model.
DIN‑Rail Mountable: Compact design fits standard 35 mm DIN rails in PV combiner boxes and DC distribution panels.
Adjustable Over-Voltage Protection – Cuts off power if voltage rises above your set safe level (e.g., 230–300 V range).
Adjustable Under-Voltage Protection – Disconnects supply when voltage falls below the safe limit (e.g., 140–210 V range).
Adjustable Over-Current Protection – Protects against excessive current with adjustable current range up to 63 A.
Real-Time Monitoring – Built-in voltage meter, ammeter, and energy (kWh) meter for live electrical data.
Delay & Reconnect Settings – Adjustable delay times before protection kicks in and automatic power reconnection after normal conditions return.
Memory of Fault Values – Saves recorded values for over-voltage, under-voltage, and over-current events even after power is off.
LED Indicators – Flashing LEDs show voltage or current protection status when triggered.
DIN-Rail Mountable – Fits easily into electrical panels using a standard DIN rail.
WiFi Smart Control — Remotely turn ON/OFF the circuit from your smartphone using the Smart Life / Tuya app.
Energy Monitoring (kWh) — Tracks real-time energy usage, including voltage, current, power, and total kWh.
Scheduling & Timer Functions — Set schedules, countdowns, and loop timers for automated circuit control.
Over/Under Voltage Protection — Protects connected equipment by tripping when voltage goes too high or too low.
Over-Current & Over-Power Protection — Trips the breaker if current or power exceeds safe limits.
Real-Time Metering — Displays voltage (V), current (A), and active power (W) in the app.
Voice Assistant Compatible — Works with Amazon Alexa & Google Assistant for hands-free control.
Relay Last Status Memory — Remembers the last ON/OFF state after a power outage.
Durable Design — Built with flame-retardant materials and supports DIN-rail installation.
