Description
The E-T-A 9000-41034-0401000 is an electronic circuit protection module from the E-TA 9000 Series (Micro Electronic Circuit Protector / Electronic Circuit Breaker), designed to replace thermal-magnetic breakers in DC control circuits. Unlike fuses or thermal breakers, it offers precise adjustable current trip, instantaneous electronic disconnection (no thermal delay for overload — follows I²t characteristic but trips faster than thermal), remote reset/switching via control input, and status output for PLC monitoring.
Based on the part number breakdown:
- 9000 → E-T-A 9000 Series electronic circuit protector
- 41034 → Specific base/module type — 1-channel, DIN-rail mount, screw terminals, 24 V DC rated (typical for 41034 base)
- 0401 → Trip Current = 4.0 A (adjustable — most 9000 series have potentiometer or are factory-set; “0401” in E-T-A 9000 coding often = 4.0A range/setting)
- 000 → Options (no extra features / standard — e.g., no auxiliary contact or special coating; verify exact dash)
Key advantages vs thermal MCB:
- No nuisance tripping from ambient temperature (electronic sensing)
- Adjustable trip current (some variants — pot on face; others factory-fixed)
- Remote Reset / Turn-On via control terminal (can be used as a remotely-switched protected 24V DC power distributor)
- Status Output (N.O./N.C.) — some 9000 variants provide a semiconductor or relay status contact to signal trip condition to PLC
The 9000 series is commonly used to protect 24 V DC control circuits (sensors, solenoid banks, I/O racks, comms modules) in machine panels — each branch gets its own 9000 protector so a short on one branch doesn’t drop the whole 24V PSU.
Key Features
- Rated Voltage: 24 V DC (typical — some 9000 accept 12–48 V DC — check label; 41034 base = 24V DC nominal)
- Trip Current: Adjustable or fixed — for 0401 = 4.0 A (typical range 0.5×–1.2× of rating depending on pot)
- Tripping Characteristic: Electronic — overload follows I²t; short-circuit instantaneous (< 0.5 ms for hard short)
- Manual / Remote Reset: Pushbutton on front + remote reset via control input (A1/A2 or separate terminal — see manual)
- Status Indication: LED (green = ON/powered; red = tripped) + optional status output (some versions)
- Mounting: 35 mm DIN rail (EN 60715)
- Country of Origin: Germany (E-T-A Elektrotechnische Apparate GmbH)

Warranty & After-Sales
- Factory new units: 12 months warranty
- Refurbished units: 3-6 months warranty (power-up + controlled overcurrent trip test — verify opens at setpoint & resets)
- Technical support for:
- Trip current setting guidance (normal load vs inrush — set ~ 110–125% of steady-state max)
- Terminal identification (power in/out, remote reset, status contact — per E-T-A 9000 manual)
- DIN rail spacing & grouping (typically 22.5 mm wide — no derating between adjacent units if well ventilated)
- Cross-ref to thermal MCB (if replacing — explain differences: no thermal memory, instant re-close after fault vs cool-down wait)
- Alternative: 9000 series with different trip (0.5A–10A range) or with auxiliary status contact (if this -000 lacks it but you need status)
- Optional DIN jumpers, marking tags
Delivery Time
