Product catalog summary

1. Product Types and Features

The ETIMAT product range includes various miniature circuit breakers (MCBs) and residual current devices (RCCBs) designed for overcurrent and earth fault protection. Key series include:

MCBs: Provide overcurrent protection with ON/OFF marking, sealing options, auxiliary device compatibility, and enhanced terminal safety.
RCCBs: Offer earth fault protection, some models integrate overcurrent protection.
ETIMAT 6 Series: Features double connection, easy DIN rail mounting, and EAN-coded identification.
ETIMAT 1N Series: Combines 1-pole plus neutral in one housing, with sealing and auxiliary device compatibility.
ETIMAT P10 Series: Premium MCBs with high breaking capacity (up to 10 kA), new mounting methods, terminal covers, locking devices, and remote control options (ETIMAT RC).
ETIMAT P10-QC: Quick connect variant with similar performance and tripping characteristics.

2. Technical Specifications

Rated Current: 0.5 A to 63 A (varies by series), extended up to 125 A for some models.
Rated Voltage: Typically 230/400 V AC; some models support DC voltages up to 440 V.
Breaking Capacity: 6 kA for ETIMAT 6 series; up to 10 kA for ETIMAT P10; higher ratings (15-20 kA) for 80-125 A breakers.
Tripping Characteristics: Types B, C, D, K, Z to accommodate different load and protection requirements.
Packaging and Weight: Detailed per product code, facilitating logistics; packaging ranges from single units to bulk packs.

3. Accessories and Additional Features

Auxiliary Switches (PS/SS ETIMAT P10): Enable remote status signaling; compact and safe-to-touch; up to two per MCB.
Shunt Trip Releases (DA ETIMAT P10): Allow remote tripping; compatible with ETIMAT breakers; available in multiple control voltages.
Undervoltage Releases (UA ETIMAT P10): Trip breakers on voltage drop; available for 230 V and 48 V.
Locking Devices and Clips: Secure auxiliary devices and ensure safe installation.
Remote Control Mechanism (ETIMAT RC): Provides remote switching with visual indicators and tamper protection.
Sealing Pieces and Marking Covers: Prevent tampering and aid identification.

4. Installation and Mounting

New DIN rail mounting method allows easy installation and replacement.
Double connection terminals enhance wiring flexibility.
Terminal covers improve safety by reducing accidental contact risk.
Quick connect terminals (ETIMAT P10 QC) support 1.5 to 4 mm² wires with easy connection/disconnection and voltage testing without wire removal.

5. Product Identification and Traceability

Each product is marked with an EAN code for easy identification and inventory management.
Comprehensive product codes cover pole number, rated current, voltage, and tripping characteristics.

6. Summary of Key Parameters

Parameter	Range/Value	Notes
Rated Current (In)	0.5 A to 63 A (up to 125 A for some models)	Varies by series and application
Rated Voltage (Un)	230/400 V AC; up to 440 V DC	AC standard; DC models require polarity adherence
Breaking Capacity	6 kA (ETIMAT 6), 10 kA (ETIMAT P10), up to 20 kA (high current models)	Higher capacity for premium and high current breakers
Tripping Characteristics	B, C, D, K, Z	Different curves for various protection needs
Mounting	DIN rail	New method for easy installation and replacement
Accessories	Auxiliary switches, shunt trips, undervoltage releases, locking devices	Enhance control, safety, and monitoring

7. Recommendations and Best Practices

Select tripping characteristics appropriate to load type and protection requirements.
Ensure correct polarity in DC installations; do not substitute two 1-pole breakers for a 2-pole breaker in DC circuits.
Use sealing pieces to prevent tampering.
Employ auxiliary switches and shunt trips for remote monitoring and control.
Follow the new DIN rail mounting method for secure and efficient installation.
Verify product codes and EAN markings for accurate product selection and traceability.
Adhere to packaging and weight guidelines for logistics and installation planning.

8. Application Notes

MCBs designed for DC circuits have specific voltage and polarity requirements.
Suitable for domestic and industrial distribution boards.
Quick connect terminals simplify wiring and maintenance.

This summary consolidates the essential technical data, product features, accessories, installation guidelines, and best practices for the ETIMAT range of miniature circuit breakers and residual current devices, supporting informed selection and safe application in electrical installations.
