Victron Lynx Class-T Power In: Setup & Busbar Guide

Key Takeaways

• The Victron Lynx Class-T Power In operates across a Voltage range 9 - 60Vdc with a massive Current rating 1000Adc continuous capability.
• Houses Two fuse connections for Class-T fuses - bolts and nuts are 3/8" and marked black to not confuse them with the M10 bolts and nuts for DC and busbar connections.
• Built with heavy-duty Busbar material Tinned copper featuring Busbar dimensions (hxw) 8 x 30mm for minimal resistive voltage drop.
• Utilizes standard Busbar M10 hardware to seamlessly bolt onto Lynx Distributor, Lynx Shunt VE.Can, and Lynx Smart BMS modules.
• Enclosed in durable Enclosure material ABS with Enclosure dimensions (hxwxd) 279 x 169 x 97mm Unit weight 2.1 kg and Protection class IP20.
• Engineered for severe environments across an Operating temperature range -40°C to +60° and Humidity Max. 95% (non-condensing).

High-Interrupt Lithium Protection & System Role

Modern high-capacity lithium iron phosphate (LiFePO4) battery banks have exceptionally low internal resistance. Under short-circuit conditions, they can deliver fault currents exceeding 20,000 amperes. Standard MEGA or MIDI fuses cannot safely interrupt fault currents of this magnitude, presenting a severe risk of arc flash or case rupture.

The Victron Lynx Class-T Power In solves this challenge by integrating two high-interrupt Class-T fuse holders directly into the modular 1000A Lynx busbar architecture.

The Victron Lynx Class-T Power In is a modular 1000A DC busbar (9 - 60Vdc operating voltage, 1000Adc continuous rating) constructed with 8 x 30 mm tinned copper and M10 busbar joiners:

• Fuse Connection 1: 3/8" Black-Marked Studs, Class-T Fuses (225A to 800A), Up to 200kA Interrupt Capacity.
• Fuse Connection 2: 3/8" Black-Marked Studs, Class-T Fuses (225A - 800A), Fast-Acting Arc Protection.

Mechanical Interconnection & Hardware Identification

The Lynx Class-T Power In connects modularly on either side of adjacent Lynx modules (such as the Lynx Distributor or Lynx Smart BMS):

• Busbar Joining: Join adjacent modules using the supplied Busbar M10 tinned bolts, washers, and nuts. Torque M10 busbar fasteners to 14 Nm to ensure low contact resistance across the solid Busbar dimensions (hxw) 8 x 30mm tinned copper conductors.
• Distinct Fuse Hardware: To prevent stripping precision threads, the module incorporates Two fuse connections for Class-T fuses - bolts and nuts are 3/8" and marked black to not confuse them with the M10 bolts and nuts for DC and busbar connections. Always use the black-marked 3/8-inch hardware specifically for mounting Class-T fuses.
