Detailed Information

Model Explanation

• EF：EMC filter + brake resistor assembly

• 030：Size/series code（higher power than EF014‑503）

• 503：Voltage/current rating（3×230–500 VAC / 10 A）

Electrical Specifications

• Rated voltage：3‑phase AC 230 V ~ 500 V, 50/60 Hz

• Rated current：10 A（at 400 V）

• Continuous power：30 W（vs. 12 W for EF014‑503）

• Brake energy：Higher absorption capacity for frequent braking

Mechanical & Environmental

• Protection class：IP20

• Mounting：Panel mount（inside control cabinet）

• Cooling：Natural convection（heatsink design）

• Ambient temp：−25 °C ~ +45 °C

• Weight：Approx. 1.5–1.7 kg

• Dimensions（W×H×D）：~60 × 130 × 260 mm

Compatibility

• For SEW MOVITRAC and MOVIDRIVE series drives

• Matches 400 V inverters up to 5.5 kW

• Replaces EF014‑503 for higher power or heavy‑duty braking

Key Features

1. Dual‑function：EMC filtering + brake resistor in one unit

2. High power：10 A / 30 W, suitable for 3.0–5.5 kW drives

3. EMI suppression：Reduces conducted/radiated interference

4. Regenerative control：Absorbs energy during deceleration/stop

5. Compact & reliable：Saves cabinet space, long‑term industrial use

Applications

• Conveyors, cranes, lifting equipment

• Packaging, material handling, machine tools

• Any 400 V AC drive system with frequent braking or high EMI
