3VL3725-2DC36-0AA0 — Siemens SENTRON 3VL Molded Case Circuit Breaker
The Siemens SENTRON 3VL is the robust, industrial-grade moulded case circuit breaker complementing the 3VA in Siemens' SENTRON protection range, purpose-built for main distribution and sub-distribution protection in demanding industrial and commercial applications. Covering 100 A to 1600 A in a compact housing with breaking capacities up to 100 kA at 400 V, the 3VL is available with thermal-magnetic (TM) or electronic (ETU) trip units. The TM version provides factory-calibrated, maintenance-free overcurrent protection ideal for straightforward applications. The ETU version adds independently adjustable L, S, I, and G thresholds, enabling protection coordination with upstream and downstream devices in complex distribution hierarchies.
The 3VL's reinforced housing and contact system are designed for vibration and mechanical shock levels found in industrial motor control, generator protection, and mobile distribution equipment — greater mechanical robustness than standard distribution MCCBs. The current-limiting 3VL1 version limits peak fault current significantly below the prospective level, reducing the required fault current rating of downstream switchgear, cables, and transformers. Breaking capacity up to 100 kA at 400 V covers fault current levels encountered at LV busbars close to large industrial power transformers in major Saudi distribution systems.
In Saudi Arabia, the 3VL is the standard sub-distribution MCCB for industrial projects at MODON estates, oil & gas temporary and permanent power distribution boards, construction site distribution, and secondary distribution panels where the 3VA's ETU communication features are not required but breaking capacity and robustness are priorities. SEC-approved panel builders in Riyadh and Dammam stock 3VL in common ratings for fast-turnaround sub-distribution board and motor feeder panel assembly.
Razz Middle East stocks SENTRON 3VL MCCBs from 100 A to 1600 A in TM and ETU versions for immediate delivery throughout Saudi Arabia.

Key Features & Benefits
- Thermal-magnetic (TM) version provides factory-calibrated, maintenance-free overcurrent protection for straightforward sub-distribution applications where adjustable settings and digital communication are not required.
- Electronic trip unit (ETU) with adjustable L, S, I, and G thresholds enables precise protection coordination in multi-level distribution hierarchies, replacing fixed TM curves with optimised system-matched settings.
- Current-limiting 3VL1 limits peak fault current significantly below the prospective level, reducing required fault current ratings of downstream switchgear, cables, and transformers in system design.
- Reinforced housing and contact system for industrial vibration and shock levels provides greater mechanical robustness than standard MCCBs in motor control, generator protection, and mobile distribution applications.
- Breaking capacity up to 100 kA covers fault current levels encountered at LV busbars close to large industrial power transformers in Saudi petrochemical and utility distribution systems.
- 4-pole configuration with switchable neutral provides complete isolation of all conductors including neutral in TN-C-S distribution systems required by IEC 60364 for certain industrial facility distribution configurations.
- Wide accessory range including undervoltage release, shunt release, auxiliary contacts, and alarm contacts allows remote switching, fault signalling, and interlocking without additional relay modules.
Industrial Applications in Saudi Arabia
- Sub-distribution board main and outgoing protection in MODON industrial estate manufacturing facilities, where 3VL TM breakers provide reliable overcurrent protection at competitive cost.
- Oil & gas facility site distribution board protection at ARAMCO temporary and permanent construction projects, where 3VL robustness handles mechanical stresses of mobile power distribution equipment.
- Generator protection and output switching at Saudi industrial facility standby power systems, where the 3VL's breaking capacity handles generator fault contribution and the TM curve accommodates the short-circuit characteristic.
- Motor feeder protection in existing Saudi industrial MCCs where mechanical robustness above that of standard MCBs is required for motor feeders above 100 A.
- Construction site distribution board protection for major Saudi Vision 2030 construction projects, where 3VL's robust construction handles rough handling of temporary site electrical equipment.
- Commercial building sub-distribution panel main breakers, where the 3VL's compact size versus ACBs reduces panel dimensions while maintaining breaking capacity needed near main substations.
- Coordinated distribution hierarchy with 3WL or 3VA main breakers and 3VL sub-distribution breakers in industrial LV switchboards, achieving selective fault isolation per IEC 60947.
