It uses a 100A:50mA transformer ratio and a wire-end connection, giving installers a direct lead option for control cabinets, electrical panels, and onboard power systems where the current sensor needs to be placed away from the inverter\/charger.\u003c\/p\u003e\u003cp\u003eIn a marine installation, this current transformer helps the Victron system read current on an external AC conductor without routing that conductor through the inverter\/charger itself. That makes it useful for boats using shore power, generator input, or energy storage setups where PowerControl, PowerAssist, or self-consumption control depends on accurate external current sensing.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e100A:50mA current transformer ratio for external AC current sensing in compatible Victron systems.\u003c\/li\u003e\n\u003cli\u003eWire-end version from the CTR12xxxx range for installations that need bare lead termination rather than a jack connector.\u003c\/li\u003e\n\u003cli\u003eCompatible with Victron MultiPlus-II and MultiGrid-II inverter\/charger systems for PowerControl, PowerAssist, and self-consumption applications.\u003c\/li\u003e\n\u003cli\u003eAvailable with 1 m, 5 m, and 20 m wire lengths to suit short cabinet runs or longer cable paths across an onboard electrical layout.\u003c\/li\u003e\n\u003cli\u003eAllows AC current to be measured on an external conductor without sending that conductor through the inverter\/charger.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis product is offered in three wire-length configurations. The current transformer function, 100A:50mA ratio, wire-end connection style, and MultiPlus-II \/ MultiGrid-II application remain consistent across the range.\u003c\/p\u003e\u003cp\u003eThe length difference helps match the sensor to the physical layout of the boat, especially when the measured AC conductor, distribution panel, and inverter\/charger are not mounted close together.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCTR120000500 with 1 m wire length. This length suits compact installations where the current transformer is mounted close to the Victron equipment or within the same electrical area.\u003c\/li\u003e\n\u003cli\u003eCTR120000550 with 5 m wire length. This option gives more routing room for panels, lockers, or equipment spaces where the sensor and inverter\/charger are separated by a moderate distance.\u003c\/li\u003e\n\u003cli\u003eCTR120002050 with 20 m wire length. This length supports longer cable paths across larger boats or distributed AC layouts where the sensing point is well away from the inverter\/charger location.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe current transformer is placed around the AC conductor that the system needs to monitor, then wired back to the compatible Victron inverter\/charger input for current sensing. It is a practical fit for shore power and generator management layouts where the electrical system needs to limit input current or supplement incoming AC power during short demand peaks.\u003c\/p\u003e\u003cp\u003eFor clean onboard integration, plan the wire length before installation and route the lead away from unnecessary strain, sharp edges, and high-heat areas. The 1 m version works well in close-mounted electrical boards, while the 5 m and 20 m versions give more freedom when the AC distribution point and inverter\/charger are installed in different spaces.\u003c\/p\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis wire-end current transformer belongs with Victron MultiPlus-II and MultiGrid-II systems that use external current sensing. It is a good match for boat owners, marine electricians, and system builders working on inverter\/charger installations where shore power limits, generator loading, and energy flow need to be managed from a measured AC conductor.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"1 m","offer_id":52581995708597,"sku":"QBP888544-V1","price":37.62,"currency_code":"USD","in_stock":true},{"title":"5 m","offer_id":52581995741365,"sku":"QBP888544-V2","price":0.0,"currency_code":"USD","in_stock":false},{"title":"20 m","offer_id":52581995774133,"sku":"QBP888544-V3","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1336481_qbp888544.webp?v=1780202252","url":"https:\/\/www.qualityboatparts.com\/products\/qbp888544","provider":"Quality Boat Parts","version":"1.0","type":"link"}
