Technical Parameters
Parameter Category Specification
Product Series System Pro M compact - GSE Series
Device Type Miniature Circuit Breaker (MCB), 3-Pole, with Special Auxiliary Protection
Standard Compliance IEC/EN 60898-1
Number of Poles 3 Poles (3P) for main circuit protection.
Rated Current (In) & Characteristic C32
• C: Tripping Characteristic (Instantaneous trip range: 5 to 10 times In). Suitable for general purposes with moderate inrush currents.
• 32: Rated Current = 32 A per pole.
Circuit Type AC ONLY (as indicated by AC).
Rated Operational Voltage (Ue) 400/690 V AC
Handle Type L - Side-operated rotary lever handle. Provides clear ON/OFF indication and comfortable manual operation.
Special Feature /0.03 - Integrated 0.03A (30mA) protection element.
• Likely Configuration: This is not a standard RCBO (residual current) trip. It is most plausibly a separate, very low-current fuse or electronic protector embedded within the MCB housing.
• Protected Circuit: This likely protects a separate pair of terminals (e.g., auxiliary contacts 13-14 or a dedicated control input) used for remote signaling, undervoltage release (MN) coil, or self-powered electronic logic within the breaker. Its purpose is to prevent damage to external control devices if a fault occurs in that circuit.
Breaking Capacity (Icn) Typically 6 kA or 10 kA at 400V AC for the base GSE203 model. Higher capacity versions exist (e.g., H version: 15 kA).
Energy Limiting Class 3
Electrical Life ≥ 20,000 cycles at rated current
Mechanical Life ≥ 20,000 cycles
Terminals Screw-clamp terminals for main conductors. Additional small terminals likely for the /0.03 protected circuit.
Mounting Standard 35 mm DIN Rail (EN 60715)
Width 54 mm (3 module width)
Ambient Temperature -25°C to +55°C
Protection Degree IP20
The ABB GSE203L AC-C32/0.03 is a highly specific configuration of a three-pole (3P) miniature circuit breaker (MCB) from the ABB System Pro M compact GSE series. It features a side-operated lever handle (L), is rated for alternating current (AC) circuits only, and includes an integrated, very low-current (0.03A/30mA) protective element. The "C32" indicates both its tripping characteristic and rated current.
